    Can the sender uncover my IP address if I reply to their email? And, would they be able to recover my IP from the computer from which I downloaded the email?

    I am using Apple Mail and POP currently. Would I be more secure in using GMail (thanks Jamie!) or Yahoo Mail?

    I just emailed myself and can see my IP address in the header.

    That is the most suspicious thing I have ever read at MR. Nice job, Lacero. :p

    Now do what all criminal masterminds do.......go to your public library and send the mail from there. If there are security cameras, don't do it. If they choose to, they could look at the time you sent the email, check the surveilance tapes during that time, and get a clear view of who you are.

    Or go to your friends house and email from there.

    Good luck.

    (I saw and heard nothing)...

    Your suggestions will come in handy one day.

    The problem I am having now is I suspect someone may be stalking me. It's a long story so I shall not burden you with the details. No criminal intent on my part. :p

    Thanks Abstract.

    Also Nermel, I've figured out how to view my source headers. Thanks, also.

    If you want to do your mailing from the comfort of home, cotse.net or a similar proxy service would take care of your problem. Just make sure to send test messages to yourself and check the headers, as some mail programs try to helpfully insert identifying information in case the server "forgets".

    Can you hook up your computer to your mobile phone and use that as your internet connection?

    um... public wifi hotspots (or better yet wardriving ) could work to the evildoer's advantage...

    but back to the task at hand, stalking is a serious matter. I would say it's worth it to get proper help and advice rather than winging it yourself.

    Is there any recourse for a person being stalked in the UK? I think in America they don't take you seriously unless you have money, or they have physically threatened you (or done something to you). That could just be my more jaded than usual viewpoint today though.

    If your mail system has webmail sign in there, that may make it so it uses your ISP or mail providers IP address.

    yea...

    I think in all cases you're better off using Gmail or Hotmail if complete anonymity is what you're after. I too use the regular mail account provided by my ISP, but only for business and/or family. For friends and acquaintances (and even this forum) I use one of two separate hotmail accounts.

    I'm curious though...does your IP address not change upon each log in? I'm fairly certain mine does, and I'm assuming my ISP assigns me a new one with each new session. Seems like it'd be much easier for the ISP to use a DHCP kind of set up rather then actually reserve a particular address for me...

    stalkers...ew. You're a very lovely girl...maybe you'd be wise to remove the pic from your profile?

    cheers

    LOL

    beatsme, you're new here. Just a wee hint -- avatars are not necessarily the actual person (or gender, or in my case, species) who is posting....


    'scuse me while I go back to chewing my cud... ;)

    Ahhhh, Lacero, I love you. :)

    Can you use a proxy server, if you have access to one, and if you do, will it be the farthest upstream you can be traced? Unless you're affiliated with a university, though, you might not have a free proxy server.

    Oh, Lacero, in answer to your edited-in question...if you use G-Mail or another service and send mails from the web-based element of it -- like if you log into G-Mail or Yahoo mail through your web browser -- you should not be able to get an IP that goes farther back than Yahoo itself in the IP trail. That is, your own IP would be shielded.

    You'd probably be best off changing your email address completely. When I was in a similar situation (very scary ex-boyfriend) I ended up having to create one new email address for any online services (myspace, forums, facebook, etc) and another that I only give out to people I trust. A bit of a hassle, but eases the worry. Yahoo mail seems to be very secure, I use it for my online stuff.

    Unless you're paying extra for the privilege of a static IP, just turn off your cable/DSL modem for a couple of min. and it should be different on startup. Correct me if I'm wrong anyone :eek: :cool:

    I don't think so...and least not if modems work the same as computer(i think they would) With computers undermost systems, there is a DHCP lease time, for windows when it is half way done it will attempt to contact the same DHCP server as it got its previous lease from, it will attempt to get the same IP as before. If it can not get the previous IP it will take any IP from the DHCP server after 3/4 of the time has passed it will attempt to get a lease from anyone it can, any server it is willing. Then if it can't get one it will drop its lease when it expires and have no IP. It will then continue to try until it gets one, but you will have a local assigned IP address (not a good idea) On boot up it will check with the DHCP server to see if it can still use the current address, if it can't it will change. So if that is the same as modems, it will keep the IP over shut down, unless someone else taken the same IP, which will normally not happen(with server 2003 DHCP service) correct me if I am wrong. :D

    Your solution to all anti-stalker needs.

    i think most cable internet providers have dynamic IP addresses that change on their own every week or two. (this is the case with mine, with comcast) unplugging is a reset of sorts but it doesn't usually change the IP address that i know of.

    My dynamically-assigned IP address (from TimeWarner here in Charlotte) has not changed in about a year... and that's with quite a few cable outages in the interim.

    Question: Is it even possible for a stalker, even if they have your IP address, to be able to tie that to a specific physical location? Seems to me like they'd be able to identify your town, perhaps, but no more precisely than that.
